There is a sale on Bernat Bamboo, Cashmere, Soy & Alpaca (2/$6, regularly $3.99 each) and I am looking for opinions since I have never used any of these before. (My experience is limited to Red Heart Supersaver acrylic and Cascade 220 Superwash wool.)

Has anybody used any of these before? Is it worth picking up and trying a couple of skeins?

They also have Bernat Max on sale (2/$8, reg $4.99 each); I really don't know anything about Bernat yarn at all so any opinions would be helpful.
